text: The triflate ligand is labile, reflecting its low basicity. Trifluoromethanesulfonic acid reacts exothermically with metal carbonates, hydroxides, and oxides. Illustrative is the synthesis of Cu(OTf).
  Chloride ligands can be converted to the corresponding triflates:
  This conversion is conducted in neat HOTf at 100 °C, followed by precipitation of the salt upon the addition of ether.
